The statement that describes the change in energy as one slide from the top is the decrease in the gravitational potential energy is equal to the increase in kinetic energy.
<h3>What is Kinetic energy?</h3>
This is known to be a kind of energy that is seen in an object or a particle due to its motion.
Based on the above scenario, As the block goes or slides down, its potential energy is known to lower or decreases and its velocity is said to increases and therefore, it's kinetic energy is increasing.
See options below
O The decrease in the gravitational potential energy is equal to the increase in kinetic energy.
O The sum of the kinetic energy and the gravitational potential energy changes by an amount equal to the energy dissipated by friction.
The gravitational potential energy and the kinetic energy must both decrease.
The gravitational potential energy decreases, and the kinetic energy is constant.

The positive aspects of free enterprise are;
- Better quality.
- Lower prices.
- Freedom of choice.
Possible limitations are;
- Lack of fair competition.
- Potential for higher prices.
- Need for consumer knowledge.
<h3 /><h3>What is a Free Enterprise?</h3>
A free enterprise is a sort of economy where the market, and not the government determines the prices of goods and services.
Since the price is a major player in this sort of economy, competitors will be forced to align their prices with the market.
Thus there will be lower prices. However, there might also be a potential for higher prices and unfair competition.

Answer:
Exercise is often described as training and should include:
<h2>exertion of the muscles</h2>
There are different reasons why things happens. If differential heating did not occur on earth, then there no global warming or global cooling will take place in the atmosphere.
When the Earth flat surface is facing the sun, all its part of that surface would get the same level of incoming solar radiation but the fact remains that due to the Earth being spherical in shape, sunlight is therefore not distributed evenly over the Earth’s surface and as such all the regions of Earth will be heated to different degrees.
Thus, differential heating of Earth’s surface takes place due to different reasons.
